This is the initial commit of the netconf server code.  It consists
of the following:
1) The server is built using Twisted Conch
2) It adapted an existing opensource netconf server (https://github.com/choppsv1/netconf)
   to handle some low-level protocols.  The adaptation is mostly around
   using Twisted Conch instead of Python Threads
3) A microservice to interface with Voltha on the SB and Netconf client on
   the NB
4) A set of credentials for the server and clients.  At this time these
   credentials are local and in files.  Additional work is required to
   secure these files
5) A rough-in to handle the rpc requests from Netconf clients
6) Code for initial handshaking is in place (hello)
